<!-- NOTE: This bug was triggered by scrollbar opacity-fading, so this
|
|
testcase needs to be loaded with this pref...
|
|
layout.testing.overlay-scrollbars.always-visible
|
|
...set to *false* in order to have a chance to trigger the bug.
|
|
|
|
We don't have to worry about this producing any screenshots of
|
|
unpredictable partially-faded-scrollbars in our reftest snapshot,
|
|
because our scrollbars don't actually paint here, since the
|
|
scrollable element has "overflow:auto" and doesn't overflow
|
|
(because it's auto-sized to fit its content). -->

.container {
|

display: flex;
|
|
overflow-y: auto;
|

border: 1px solid black;

// NOTE: setTimeout in tests is evil, but it's necessary here -- we need
|
|
// to wait until the scrollbars have finished fading, and there's no
|
|
// event we can listen for to signal that, AFAIK. Fortunately, there
|
|
// shouldn't be *visible* scrollbars in this testcase, so even if our
|
|
// setTimeout fires too early/late, the test will still pass. (So, there
|
|
// shouldn't be spurious failures; any failures that happen will be real.)
